srncrrrcA'rroN forming part bya fan or blower through pipes which-pass through the said reservoir in a coil of any necessary length, to cause the air to be heated or cooled, as the case may be, to the necessary extent, by the contact oi' the hot or cold water with the said-coil. Inwinter the heated airis introduced into 'the car near the floor. In summer the cooled air is introduced at the upper part ofthe car.

My invention further relates to a new auch improved construction of exit-valves for controlling the direction of the currents of hot or cold air, so as to distribute the said currents, or to locate them, as maybe agreeable to the several occupants of the car.

In the accompanying drawings, Figure l is a vertical longitudinal section of a portion of a car-body with my invention applied. Fig.2 is a transverse sectiouoi the same ou the line 2 2, Fig. 1. Fig. 3 is a vertical section of the water-tank, showing the crate applied within the coil of air-pipe to contain ice and protect the said pipe frominjury therefrom. Fig. 4. is a transverse section of one of the exit-valves on a larger scale. l

A 'represents a heating-stove, the" smokepipe B of which preferably passes up through the interior of the water-*tank- U, which surmounts Vthe said stove and containsa coil, D, through which airis forced .by afan, E,driven by any suitable motor. For this purpose I prefer to use the spring-motor shown at F, which I have made the subject of a separate application for Letters Patent.

The coilI) is made of very thin metal, preferably copper, so as to transmit the heatirom the watel.l to the air with the greatestfree'dom, and for summer use l employ a crate, 1t, Fig. 3, to contain ice and protect the thinmetal pipe from injury.

with the exterior of the air-pipeimparts heat to the air very rapidly and eflectively-,but

without the possibility of overheating. 'The air is conducted lfrom Vthe tank by a pipe, Gr, connecting with the coil D, and by adowih ward branch, Il, to-a pipe or box, I, which extendsalong the iioor of the car againstthe wall, and is made very narrow lin a horizontal direction to avoid taking up' much floor-room.

J J are registers for regulating the admission of heated air to the interior of the carnear the iloor. In asleeping-car I employ 'vertical pipes K K, rising' from the horizontal-pipe l', for supplying fresh warm air to the'lower' and upper berths through valves L L. Y

rIhe air is .carried from one side of the car to the other by means of a bridgepipe, M, above the doorway, so as to `avoid obstri'ieting the passage. 'lhe pipe M communicates with a' -I 'Ihccoutact of the hot wat'erof the tank" second hot-air box, I, on the other side of the y The same arrangement of blower and supy ply -pipes and valves is used for supplying cold air in summer; but as it is desirable to introduce cool 'air in summer near the top of the car, instead of near the floor, as in the case of hot air in winter, I employ one or more horizontal pipes, N N, communicating with the pipes G and M, and running from end to end of the car directly underneath the dome or roof, and provided at any desirable intervals with valves L2. v

In order to ca ise a more free and continuous circulation of air, I connect the vertical pipes G and horizontal pipes NN, as shown in Fig. l. rIhis combined system of pipes forms au excellent arrangement for suppl yin g fresh air to the interior ofthe ear at all seasons, as Well dur# For cooling the air in very hot weather the 'tank C is filled with ice-water, the contact of which with the exterior ofthe pipe D reduces the temperature of the air as low as desirable. The air isp'uriiied and dustv etfectually excluded by twoy or more screens of wire-gauze of successive` ueness, one orlmore sheets of hunting, and, if needful, a sheet ot' closer cloth inside of this, all applied to the-open exterior window ofthe apartment in which the blower is placed.

As a further protection against d ust, I keep the cloth saturated with water, or, it' preferred, Ipropose to employ any suitable and customary' device for .passing the air through water.

A full supply of fresh air being 'thus introduced into the car, the air will be constantly changed, and vitiated airremoved through ventilators O 0, guarded on thc outside by shutters l) P, made of `light wood and so hun gas to open freely to pass foul air out, but to close instantaneously against felt seats p on the slightest current or pressure from without, so as to prevent the ingress of. smoke or dust or external air, which in winter will be colder and in summer warmer, and at all times less pure than that supplied through lny'mechanical ventilator. Similar shutters are provided, as shown at P in Fig. 2, in the lower parts of the cardoors, ,if desired, to take the vitiated air ont near the door, and thus economizc heat in cold4 weather.

In order to Aprevent an excessive ilow of hot air to the upper pipes at the expense ot' the 4 boxes I I near the iioor,where the heat is most advantageously applied, I use a valve or damper, Q, in the ascending pipe G, and in like manner, to prevent the excessive down ward ow of cold air in summer, I propose to apply a similar valve or damper, Q', in the descending pipe H but this is not so necessary.

S represents a blast-pipe leading from the fan-case to the lower part of the stove, and controlled by a valve, T, for the purpose ot' urging the ire when needful.

'The mode of constructing the air-discharging valves L L L is best shown inI1`ig. 4,where 1 represents a part of the pipe to which the valve is applied, and 2 a sleeve surrounding it and turned by a handle, 3. The interior i pipe, 1, has a wide slot ,nearly as long as the sleeve 2, and extending around onethird\lor one-halt' the vcircumference of the pipe. The sleeve 2 is formed with 'a slot, 4, adapted to register with theslot in the inner tube, but very much narrower. 'IheV sleeve is thus adapted vto completely close the opening in the pipe or to expose an orifice of any size on either side of the pipe. Jets or currents of air are thus produced in any desired direction, and by using a number ot' sleeves together, as illustrated in Fig. 1, I am enabled to discharge a number of currents in different directions from one center,I so as to cool or heatand ventilate every part of the ear and suit the requirements of the various occupants.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. The combination ofthe blower E, tank C, air-pipes D G H I, and valves L, substantially as and for the purposes set forth.

2. The combination, with a main pipe and pipes G H I K, of valves L, each eonsistingof an internal pipe, 1, slotted or cut away around about one-third (more or less) ot' its circumference, and a rotating sleeve, 2, having a narrower slot for the purpose ol' discharging a jet of air in various directions radial to said pipe.

3. The combination of' the blower F E, the pipes J) G 1I I, the outlets O, and shutters I, substantially as and for the purpose set forth.

4. The combination ofthe stove A, heatingtank C, air-coil 1), blower E, and the blastpipe S, for urging the tire, substantially as and for the purposes set forth.
